There’s no right or wrong answer. This decision can’t be based solely on which fuel is cheaper and easily available as there are many factors to consider, both options have their pros and cons. Here is a comparison between the two fuels.

Environmental Concern

Purchasing a lawn mower is no exception, when you purchase home and garden products you must have to consider the health of your family, people landscape, and the health of environment. Both diesel and petrol are refined from crude oil but the diesel fuel is dirty and not pollution free, causes dirty emissions, tend to produce more dark smoke and more harmful against petrol for the environment. This is the primary reason why many people choose to use a petrol mower and the mowers have gained popularity all over the world.

Financial Concedration

Diesel was cheaper than petrol in past but now its more expensive,  a very high price difference between this fight so they are not both about the same when it comes to the price of the fuel itself. Petrol mowers are also cheaper as new purchase and diesel mowers also tend to be more expensive and Diesel fuel is less readily available than petrol these are also the reasons why many people choose a petrol mower.

But As a fuel, diesel is more efficient than petrol, meaning that it produces more energy per given volume of fuel. That means for every gallon of diesel fuel you burn in your mower, you’ll get up to 12 percent more output from the engine than a gallon of petrol in a petrol-powered mower, result is a better mileage, so there is also a saving in that direction. Diesel engines offer more torque than a petrol engine, this allows great acceleration, which also accounts for the great fuel economy numbers. Diesel engines may also have a longer life than petrol engines, which will reduce maintenance and replacement costs.

Noice & Smoothness of Ride

. This is another area where the petrol mowers can easily kick out the diesel mowers. Diesel engine produce horrible roaring noises, it is still louder than the any other mowers. Diesel produces smoke nearby and are much noisier and tend to vibrate. You will also experience less of a smooth ride from your engine, which can make the round a less pleasurable experience.

Tend to Use

If you are making long stripes in a very wide job site or running up and down on hills then diesel mower is an obvious choice. Diesel engines adjust their air-to-fuel ratio depending on how hard they are working and produce MaxTorque, transmit more efficient power to the cutting system allowing the mower to cut the grass more efficiently in hard-working conditions, especially in wet, heavy or thickly Bahiagrown  grasses.In large properties or industrial park mowing a powerful mower is better able to accomplish these difficult jobs quickly, saving both time and fuel on each job site.    But if you have a medium or wide flat yard and normal turf to mow, a petrol mower suit your needs. If you make short smooth stripes then petrol would be a more sensible option.

Engine Performance

First, the diesel engine doesn’t have the parts that usually wear out or give problems. There are no spark plugs, rotors, points, or distributor caps, no carburetor that is going to gum up and be hard to start after being stored for a long period. Second, Diesel fuel and engine combination can produce better engine performance, although this is lessened when the diesel use is bio-diesel, or other forms of enhanced fuel such as black diesel. Diesel engines deliver more power per stroke than petrol engines do; the power difference helps diesel engines to be more efficient than petrol engines, since they can do more work in a given amount of time and fuel.

During frigid weather, diesel engines have a propensity towards gelling up. To fight this, many people who have diesel engines must have an engine block heater installed or keep their device running during colder weather. If you live in a warmer area, where freezing is not an issue, your diesel mower will be more fuel efficient. Diesel engines are harder to start, gives Sluggish performance in cold climates if they contain glow plugs, diesel engines can require you to wait before starting the engine.

Conclusion

You have to choose the right one; follow the tips when weighing the options.

1- Determine the size of your mowing needs and your priorities. Organisations need to sit down and determine the size of their mowing needs because fuel options will vary among mower sizes. The next thing to do is prioritize what’s important to the organisation in terms of sustainability, financial impact, and continuity with the rest of the fleet. For example, if a large percentage of an organisation’s fleet runs on diesel, it makes sense to stick with what they know, for example Army.

2- Make sure the mower will stand up to the needs and assess the costs. Make sure the equipment will hold up to the mowing applications required, regardless of fuel type, Also research how much the equipment will cost in maintenance and upkeep throughout the duration of the expected service life.

3- Compare current and future costs. Review fuel use and costs from previous years thoroughly and compare how the available fuel types will affect costs over the expected life of the equipment.

4- Assess fuel availability and storage. Look at local fuel availability and price; Compare that against what you’re currently using and your storing and transporting needs.

5- Responsibilities are you may be eligible for grants related to greener fuel sources and Environmental concerns.
